Product Description
Process large batches in one spin with 250 mL and 500 mL tubes built for big-volume centrifugation. They are suited to harvesting cells, bacteria, yeast and tissue samples, clarifying supernatants and collecting sediments after chemical reactions. Bulk and racked packaging options suit both stockroom and benchtop use.
This listing is for NEST catalog number 622002: 250 mL Large Volume Conical Centrifuge Tube, Polypropylene, Plug Seal Cap, Racked, Sterile, Case of 24 (4 Packs x 6). The tubes are molded from polypropylene and paired with high-density polyethylene plug seal caps, whose two-part design gives a double layer of sealing protection. A thickened conical bottom raises the maximum centrifugal force to 7,000 x g, and clear graduations aid volume measurement. Tubes tolerate -80°C to 120°C, are DNase, RNase and pyrogen free, and are electron-beam sterilized to SAL 10⁻⁶. Add it to your LIGHT LABS order and keep your bench stocked with genuine NEST consumables.
